17 Claims. I (Cl. 114-219) This invention relates generally to the anchor handling art, particularly in relation to small and medium sized boats, and more specifically to a new and useful anchor davit for that purpose.

Heretofore, the handling of anchors on small and medium sized boats has been fraught with difficulty, inconvenience and potential danger. It is possible to raise and lower anchors of this size by hand, without the aid of any mechanical means whatever, but such completely manual handling is highly incovenient, for reasons which are obvious, and places the person handling the anchor under considerable physical strain and in an off-balance and therefore often dangerous position. In addition, there is the problem of raising, lowering and stowing the anchor in a manner insuring that it will not inadvertently strike and injure the boat, and that it will not loosen in a blow and cause damage to the boat or injury to occupants thereof.

While numerous davit constructions have been proposed for this purpose, it is my experience that none of them has solved the problem to the complete satisfaction of boat owners, because they have been either completely impractical, too complex and/or expensive, too apt to become fouled, not consistently dependable, or have presented some other disadvantage.

Accordingly, it is a primary object of my invention to provide a davit construction, particularly adapted for use with boats, which is quickly and easily operated to raise, lower and/or stow an anchor in a manner precluding accidental striking of the anchor against the boat.

Another object of my invention is to provide an anchor davit having the foregoing advantageous characteristics and which is relatively simple and inexpensive in construction, while being extremely durable and dependable in operation.

In one aspect thereof, an anchordavit constructed in accord with my invention is characterized by the provision of a support movable on a base between anchor stowed and anchor lowered positions, a pulley mounted on the support, a rope trained over the pulley and carrying an anchor, means for holding the anchor against lowering movement relative to the support, and means responsive to swinging movement of the anchor toward the support as the anchor is raised thereby to actuate the holding means.

In another aspect thereof, an anchor davit constructed in accord with my invention is characterized by the provision of a base, a support mounted on the base for movement between anchor stowed and anchor lowered positions, a pulley mounted on the support, a rope trained over the pulley and an anchor carried by the rope, the support being adapted to receive the anchor thereagainst for stowing or chocking, together with means automatically holding the anchor against lowering movement relative to the support and thereafter chocking the anchor nited States Patent securely against the support for stowing as the support is moved from anchor lowered to anchor stowed position.

"Rte

In still another aspect thereof, an anchor davit constructed in accord with my invention is characterized by the provision of a support pivoted on a base between anchor stowed and anchor lowered positions, a pulley mounted on the support, the pulley being arranged to have an anchor rope trained thereover, and spring motor means for moving the support out of its anchor chocked position including a housing, a plunger movable relative to the housing and projecting therefrom, spring means carried by the housing and normally biasing the plunger to its fully projected position, the motor being pivoted to the base in spaced relation to the support for movement about a generally parallel pivot axis and being adapted to be engaged by the support as the latter is pivoted toward its anchor stowed position whereby anchor stowing movement of the support telescopes the plunger into the housing to store up energy in the spring.

The foregoing and other objects, advantages and characterizing features of an anchor davit constructed in accord with my invention will become clearly apparent from the ensuing detailed description of a presently preferred embodiment and one modification thereof, together with the accompanying drawings illustrating the same wherein like reference numerals denote like parts throughout the various views and wherein:

The illustrated embodiment of an anchor davit constructed in accord with my invention comprises a base, generally designated 1, adapted to be secured to the deck 2 of a boat as by means of bolts 3 or the like extending through ears 4. In addition to mounting the movable davit mechanism about to be described, base 1 also can function as a support for a housing for running lights, and the like, as indicated at 1 (Fig. 2) as will be readily apparent to those skilled in the art.

It is contemplated that base 1 will be secured to boat deck 2 at a central position in the bow, thereby enabling a support, generally designated 5, to project forwardly of the boat, ahead of the bow, when in its anchor lowered position illustrated in Figs. 1 and 2. Support 5 comprises a pair of struts o, preferably of tubular construction, each 'pivotally mounted adjacent its lower or inner end on base 1 as by means of a bolt 7 passing through an ear 7'. Each strut 6 carries at its upper or outer end a plate '8 forming part of a pulley supporting bracket, which plates 8 are welded or otherwise secured to support struts '6 and mount a pulley 8' over which the anchor rope 9 is trained. 'Pulley 8 is journaled on bracket plates 8, as by a bolt 11, and is grooved in the usualmanner to receive the rope 9.

' There is 1 shown an anchor, generally designated -12 (Figs. 3 'and 4), of a known construction which is no part of my invention, although I believe that an anchor of the illustrated construction is particularly well suited "to use with the davit of my invention. Such an anchor comprises a shank 13 slotted from one end to substantially the other end thereof, as illustrated at'14, to enable sliding movement therealong of 'a ring '15 to'which the anchor rope is connected. At its other end' the anchor shank 13 is tapered and enlarged, to provide a body portion l5 on which a pair of flukes'16' are supported for pivoting movement relative thereto limited by opposed shoulders 17 on body 15. This construction presents a very considerable advantage in thatif the anchor is caught'in one position, with the flukes' -16 looked under a projecting rock shelf, or the like, the

anchor can be disengaged by simply moving the boat to the other side of the anchor, causing ring to slide 'along'shank 13 toward the enlarged end 15', and then pulling the anchor out backwards to free it from what- 'ever obstruction it has encountered. Of course, the davit of my invention is readily adapted for use with other anchor constructions.

The anchor 12 is adapted to be raised, and the anchor and its davit are adapted to be moved to the stowed position illustrated in Fig. 4, by pulling upon the anchor rope 9, as will be described in greater detail hereafter;

For swinging support 5 and anchor 12 from the anchor stowed position of Fig. 4 to the anchor lowered position of Fig. 2, I provide means in the form of a spring motor, generally designated 19, comprising a housing 20 carried by a clevis bracket 21 pivotally mounted on base 1 as by a bolt ZZIand containing a'compression type spring 23. A plunger, comprising a rod 24 projecting answer from housing 20 is provided at its outer end with a generally U-shaped bracket 26 mounting a pulley 27.

The upper end of housing 20 is closed, as by a plug 28 held in place by a screw 29 through the wall of housing 20, and plunger rod 24 normally is urged by spring 23 to its fully projectedposition with washer 25 hearing against end plug 28.

Spring motor 19 and support 5 are provided with cooperating shoulders, for cocking the motor upon movement of the support to anchor stowed position, and whereby release of the support will initiate movement thereof by the spring motor toward anchor lowered position. To this end, bracket 26 of plunger 24 can project outwardly beyond pulley 27, to provide at its outer end shoulders 30 adapted to engage beneath and bear against a cooperating shoulder in the form of an angle 31 carried by the support struts 6 and spanning the same intermediate the opposite ends thereof. Thus, upon rearward movement of support 5 from the position of Fig. 3 toward that illustrated in Fig. 4, the outer end 30 of the motor plunger 24 will engage beneath the generally horizontal leg of support bracket 31, whereby continued rearward movement of support 5 will telescope plunger 24 into motor housing 26, compressing motor spring 23 and thereby storing up potential energy in the same. As clearly illustrated in Fig. 4, when the davit is in its anchor stowed position the motor plunger is substantially fully retracted, and the'r'n'otor thereby is taut or cocked, so that upon releasing rope 9 to permit anchor lowering movement of the davit the compressed spring 23 forces plunger 24 outwardly of motor housing 20, the plunger shoulders 30 bearing against bracket 31 to swing support 5 up and over, past its dead center point, following which the weight of anchor 12vvill contime the forward, anchor lowering movement of the davit.

It willbe appreciated that spring 23 is of substantial strength, more than suflicient to lift support 5 and the anchor 12 carried thereby from the nearly horizontal, stowed position illustrated, in Fig. 4 to a nearly straight vertical position, just before that illustrated in Fig. 3, beyond whlch=the weight of support 5 and anchor 12 combine to continue the desired forward movement thereof. While spring 23 is selected to have sufficient strength toaccomplish this, it will be seen that motor 19 reaches its vertical, dead center position prior to the time when support 5 reaches a corresponding position, because their pivot points are spaced apart fore and aft of the 'boatto which they are attached. To insure movement of support 5 past its dead center position, a torsion spring 32 (Figs land 4) is provided to swing motor 19 past dead center and tothe position illustrated in Fig. 3.

Torsion spring 32 can be mounted in base 1, which comprises a'hollow housing for this purpose, being positioned around motor pivot pin 22 and having one end bearing for example on the underside of the top wall of base .1, with its other end locked to motor support bracket 21, as through pivot pin22. Consequently, as motor 19 is cocked upon anchor stowingmovement of support 5 torsion spring 32 also is stressed" to store up potential energy therein. Such energy is released upon release of rope 9 to swing motor 19 about its pivot 22 past its dead center, position and to the position illustrated in Fig.1 3, at'which point the motor support 21 strikes abutments'or stops 33 on .t her forward movement thereof. e

' Thus, spring motor 19 is energized automatically upon moving the anchor to its stowed position illustrated in Fig. 4, and is'at all times ready, without more, to swing the anchor and its support 5 out of stowed position to lower the anchor. In addition, it is a particular feature of my invention that when support 5 is in anchor lowered position (Fig. 2), the spring motor pulley 27 receives anchor "rope 9 and the spring motor provides a lever arm facilitating lifting of support 5 by simply pullbase 1, to limit furi-ing onthe anchor rope.

' This is because spring motor 19 is held by stops 33 in a generally upright position, just a few degrees past dead center or straight vertical, whereby spring motor 19 holds anchor rope 9 well oif the deck in a substantially elevated condition relative to support pulley 8; 'lt'would be quite difficult to lift support 5 from the position thereof in Fig. 2 by pulling rope 9 if the latter-simply 'lay on deck 2, because there would be no lifting mo ment; However, with the instant invention the spring motor provides a very efiective lever arm which is fully operativewhen support 5 is in a'generally horizontal "position, making it relativelyeasy to move support '5 out of such position.

This arrangement also offers a, significant advantage with respect to load distribution, because when the an- :chor is suspended in the position of Fig. 2, as much as sixty (60) percent of the load is on spring motor 1?, and most of this part of the load is transferred by motor 19 directly to housing 1 and deck 2 in compression. This greatly reduces the efiectof the load suspended on the outer end of support 5, and thereby avoids tearing of the davit off deck 2 such as might otherwise tend to occur. e In addition to this novel anchor davit motor it is a particular feature of my invention that, upon predeter- 'mined anchor stowing movement of the davit, as when it reaches approximately the position illustrated in- Fig.

3,- the anchor is automatically held against lowering movement relative to the davit support 5, so that there is no danger of the anchor suddenly dropping at this point anddamaging the boat deck, and upon further anchor stowing movement thereof the anchor is automatically clamped to the support against movement relative thereto. In addition, means are provided to preventswinging of the anchor as the davit is raised from its lowered position to the clamping position illustrated in Fig. 3.

in the embodiment of Figs. 1-8, this is accomplished by clamping the anchor rope, and to this end, the ofiset brackets 8 mounted on support struts 6 also carry a clamping mechanism including a member 35 which has a serrated under-surface 36 facing the pulley groove and is carried by side plates 37 pivoted to brackets 8 in oflfset relation to pulley 8', as at 33. A clamp actuating member 39 also is mounted on bracket 8, comprising for example spaced side plates 41 pivoted adjacent one end on bracket 8, as at 42, and bridged by a plate 43. The anchor rope 9 is trained over pulley 8', between it and clamp part 35, and passes between the actuating member side plates 41 and through an eyelet 44, having a beveled entrance 45, carried by an end plate 46 of generally inverted V-shape in cross section. in this way, rope 9 is constrained to move through eyelet 44, for a purpose to be described. A cooperating plug member 47 has a bore therethrough terminating in a recess to receive the end of rope 9, as indicated at 48 in Fig. 5, and also pivotally mounts the anchor ring 15. At its upper end, plug 47 is formed with a tapered surface having outwardly converging sides 49 which complement and are adapted to nest with the side walls of end plate 46 for being held against swiveling relative thereto.

The V-shaped parts 46 and 47 have their apexes alined in a direction at right angles to the plane of the flukes 16, whereby as the anchor 12 is raised out of the water, by pulling on rope 9, the plug 47 engages the clamp actuating member end plate 46 and is automatically positioned thereby for nesting therewith. The nesting parts 46 and 47 hold the anchor against undue swiveling movements, such as might otherwise cause it to strike and damage the boat, as it is lifted by the davit up into stowed position on the boat. It part 47 is not alined with part 46 at the position illustrated in Fig. 7, it will automatically be carnmed thereby into proper alinement. Anchor stowing movement of support 5, caused by continued pulling on anchor rope 9, lifts the anchor 12 with the anchor and clamp actuator 39 moving substantially as a unit so that, as support 5 is moved toward the position illustrated in Fig. 3, the weight of anchor 12 swings it and actuating member 39 inwardly toward support 5 about the pivot axis 42 of member 39.

The inner end 53 of clamp 35 is formed to clear the inner end 51 of actuating member 39 whenever support 5 is between the positions thereof illustrated in Figs. 2 and 3. However, as support 5 moves to the position thereof shown in Fig. 3, the weight of anchor 12 swings it and actuating member 39 about pivot 42 causing a shoulder 52 on actuating l ember 39 to engage beneath a shoulder 53 on clamp 35, whereby continued pivoting of member 39 about its axis 42 will forcibly pivot clamp 35 about its axis 33, in a counterclockwise direction as viewed in Fig. 5, to force the clamp part 35 firmly against rope 9 and clamp it against pulley 8'. Therefore, at the position shown in Figs. 3 and 5, anchor 12 not only is held against undue swiveling, but in addition the anchor rope 9 and pulley S are clamped against anchor lowering movement. As a result, the anchor 12 cannot accidentally drop and strike deck 2- whenever the davit is between the positions of Figs. 3 and 4, this being accomplished automatically without any attention on the part of the operator, being solely in response to swinging movement of anchor 12 toward support 5 as they are moved toward anchor stowing position.

Support 5 is provided with anchor receiving means in the form of a bed comprising a plate 55 welded, bolted or otherwise secured to support struts 6, as indicated at 56, and having outwardly diverging wings 57 at opposite sides thereof, the plate 55 being adapted to receive the anchor flukes 16 thereagainst when the anchor is in its stowed position. Thus, as support 5 swings rearwardly from the position illustrated in Fig. 3 to that illustrated in Fig. 4 the anchor, which is held by nesting parts 46 and 47 and by clamp 35 with its fiukes 16 aligned to lie generally fiatwise against the plate 55, moves into that position as clearly illustrated in Fig. 4.

To securely clamp the anchor against the support 5, so that it is immovable relative to the davit when in its stowed position and cannot accidentally be dislodged therefrom and strike deck 2, I provide means in the form of clamping arms 58 of generally right angular form having one leg pivoted to the support struts 6, as at 59, and adapted to swing upwardly under and over the anchor flukes 16 to clamp them against plate 55 and thereby securely lock anchor 12 in stowed position as clearly illustrated in Fig. 4. Normally, clamp arms 58 hang free and clear of anchor 12, to permit it to move against the plate 55 as the davit moves into stowed position, and I provide means automatically operable to cause arms 58 to thereafter clamp anchor 12 in stowed position, such means comprising for example a bail-like actuator member 61 pivotally connected adjacent its opposite ends to arms 58 outwardly of their pivots 59. Actuator 61 is aligned with a shoulder or dog 62 carried by the motor housing 20, so that after support 5 moves rearwardly from the position of Fig. 3 toward that of Fig. 4 and engages plunger 24, the bail 61 is caught on dog 62. Dog 62 prevents inward movement of actuator 61 along motor housing 2t}, whereby continued rearward movement of support 5 causes upward pivoting movement of arms 58 around and over the anchor fiukes 16 to securely clamp them against plate 55 when the anchor is in its stowed position illustrated in Fig. 4.

Thus, it is seen that with an anchor davit constructed in accord with my invention, as the anchor is raised it is immediately and automatically held against undue swiveling out of proper alinement for movement into stowed position, from the time the davit begins to raise the anchor, and the anchor rope is clamped against lowering movement automatically when the davit reaches a posi tion such that if the anchor were to fall it would damage the boat. Continued movement of the davit to stowed position energizes the spring motor 19 for subsequently throwing out or lowering the anchor upon releasing the anchor rope, and automatically causes the anchor to be firmly clamped to the davit for being securely held in stowed position on deck. This is provided in a very compact structure susceptible of a highly pleasing and ornamental appearance, operable with minimum eflort and maximum dependability.

Anchor raising and stowing movement is accomplished by pulling on rope 9, which can be done manually or by an appropriate hoist, not illustrated, and anchor lowering movement is accomplished automatically, by simply paying out rope 9.

To provide clearance for end 15 of anchor 12, or as might otherwise benecessitated by a particular anchor, plate 55 can be cut away, as indicated at 64, and cushioning means 65 can be provided on motor housing 20 and/or wherever necessary to prevent marring of the davit by the anchor. Also, to help support the support 5 when in its lowered position and maintain the same free and clear of deck 2, generally U-shaped brackets 66 are provided on base 1 on opposite sides thereof ahead of the pivot 7, to receive struts 6.

Where more power is required for lifting action, multiple motors 19 can be utilized.

A modified anchor holding arrangement is illustrated in Figs. 9-12, wherein the davit pulley 8' is mounted on struts 6' which correspond to struts except that, instead of providing a pulley supportingbracket in the form of separate plates afiixed to the struts, the outer ends of struts 6' are flattened, as indicated at 6", and apertured to receive therethrough a bolt 11' carrying a bearing sleeve 70 on which the pulley 8' is journaled. Bearing carries at its end an anchor plug, generally designated 75. Plug'75 comprises a tubular body part 76 having an upper surface 77 of generally inverted V-shape, complementing and interfitting with seat 74 on guide member 72. A shouldered nipple 73 is carried by body 76 and projects through the guide surfaces 77 thereof for passing through an opening 79 in the plug receiving seat 74 and into the hollow head 73 of guide member 72. At its outer end, nipple 78 has a shouldered locking part in the form of an annular groove 81 of generally V-shaped cross sectional form. 7

Plug 75 is conveniently secured to anchor rope 9 by means including an internal sleeve 82 having a tapered aperture 83 receiving the end of the rope, and cooperating with a tapered internal plug 84 which is inserted into the end of the rope to splay the same and clamp it against the tapered aperture 83, as clearly illustrated in Fig. 10. The parts 82 and 84 preferably are molded of nylon, and serve to securely lock plug 75 to anchor rope 9, the locking action being completed by means including an external plug 86 having "a split, tubular shank 87 of generally U-shaped cross-sectional form which has threaded engagement with sleeve 76, for ramming home the internal plug 84. The plug 86 is split to receive therethrough ring attached to shank 13 of anchor 12, and can be locked in place by means including for example a set screw 88 in member 76 adapted to extend between the split sections of shank 87 to prevent rotation of plug 86 In this way, the anchor attached plug 86 can be locked in the position which will maintain the anchor in proper positional alignment with support plate 55 for lying thereagainst, when the cooperating guide surfaces 74 and 77 are properly engaged as illustrated in Figs. 10-13.

A second shouldered locking part 90, having an end 91 of generally V-shaped cross sectional configuration to interfit with groove 81 in nipple 78, is carried by a generally U-shap'ed bracket 92 which is adjustably locked against movement relative to the davit support, the bracket 92 engaging on bolt 11' and being locked against movement by nuts 11". Locking pin 90 is in positional alignment with locking nipple 78 when plug 75 is properly seated in guide member 72, but does not engage the locking groove 81 on nipple 78 until the latter is swung through a predetermined angle toward davit support struts 6.

In use, when the davit is in anchor lowered condition, the parts are in the position illustrated in Fig. 9. However, when the anchor is raised, plug 75 engages the davit guide member 72 and the guide surfaces 74 and 77 cause the plug to seat in a predetermined. manner to maintain a predetermined positional alignment of the attached anchor 12 relative to the davit support plate 55, so that the anchor will be received thereagainst in the manner easiest this way spring93, through its arm' 95, resiliently resists upward movement of guide member head 73, causing plug 75 to properly seat therein even if plug surface 77 is initially completely out of alinement with the guide member seat 74, i

K It will be noted that when plug 75 is properly seated, locking nipple 78 projects through the guide member seat into the hollow interior thereof, in alignment with locking pin 90. Then, continued pulling on anchor rope 9 causes the davit to swing rearwardly in the manner previously described, with the struts 6' moving in the direction of arrow 96 (Fig. 12). During such anchor raising movement of the davit the weight of anchor 12 and attached parts causes them to swing inwardly relative to support struts 6 about the pivot axis defined b'y shaft 11', in the manner previously described with reference to Figs. l-8,

until locking pin 90 engages locking nipple 78. Once these locking parts are engaged, which occurs at about the position shown in Fig. 12, anchor plug 75 is locked against guide member seat 74, and stays locked there against when the davit is between this position-and its anchor stowed position. When locked against seat 74, it is impossible for the anchor to drop downwardly relative to the support. The locking arrangement is engaged automatically by movement of the anchor toward the support, and are held engaged by the weight of the anchor, as in the embodiment of Figs. l-7, but all of this being accomplished in the instantembodimcnt without touching rope 9 and therefore without injuring the same. It is believed that this is the preferred method of holding the anchor, because it avoids clamping against the rope which clamping produces wear thereon.

Where it is desired to vary the point at which locking parts 90 and 78 engage, the position of locking part'90 relative to support struts 6 is readily adjusted by momentarily loosening nuts 11".

Also, the arrangement illustrated in Figs. 9-13 has the further advantage that the rope is subject to less wear and tear in its operation through guide member 72. This is because the latter is maintained in its proper position by its own weight and by spring arm 95, and the anchor rope is confined for a considerable portion of its outer end in the nipple 78, whereby there is little or no abrasion of the anchor rope.

Of course, the inner ends of strust 6' can be flattened, similar to outer ends 6", for attachment to the base 1. Otherwise, except where noted above the davit of Figs. 9-13 is the same as that illustrated in Figs. l-8.

Accordingly, it is seen that an anchor davit constructed in accord with my invention fully accomplishes the intended objects. While only a presently preferred embodiment and one modification have been disclosed and described in detail herein, it is to be understood thatI do not'thereby intend that my invention be limited to such details. Instead, 'I realize that other modifications and variations will readily occur to those skilled in the previously described.
